The light helps you to keep an eye on your food without opening the door and letting the heat out; this is particularly important when you're baking a cake because opening the door prematurely in that situation will lead to some serious sponge sinkage!
I turn on the oven light when I'm cooking anything in the oven. That way, I just lean over and check what I'm cooking without opening the oven door. The light bulb uses less than a cent of energy per hour of use, so the cost is virtually nil if I flip it on, inspect the food, and flip it off.
Yes, you can use your oven without a bulb. The bulb in an oven is primarily for lighting the interior so you can see your food while it cooks. It does not affect the cooking functionality or temperature of the oven.
Jon Grella : Usually if the light in the oven is on it usually means that either the door is open or not closed fully. Enough so that the door switches not closed. And the door switch is what keeps the light on in the oven.
That light is to let you know that the burner WAS on. The light usually turns on when you turn the burner on and will stay illuminated even after you turn the burner off until that particular burner has cooled down and isn't a burn hazard to you.
The incandescent cooktop light makes cooking easier by providing a sufficient amount of light to the cooktop surface. The incandescent cooktop light can be used as an aid in cooking, or even as a night light for your kitchen (on models so equipped).
Most newer gas ranges and ovens don't have pilot lights. Instead, the gas is ignited by an electric ignition system. In this type of system, an element becomes hot and glows like the filament in a lightbulb when an electric current passes through it. The heat from the filament lights the gas.
A broken hot surface switch on one of the burners causes the Hot Surface light to stay on constantly. To find out which surface element to replace, you'll lift the glass cooktop and test each of the hot surface switches using a multimeter.
Modern ovens are designed to have the light on for extended periods without causing any harm.
To reach higher temperatures of 350-400ºF, it will typically take about 15-20 minutes to preheat.
Most modern ovens come fitted with lights - they come on when the oven is on, and switch off when the oven is off.
Leaving your oven on all night puts you at risk for an oven fire. Not only will you be risking fire hazards, but the gas that comes from your oven can lead to carbon monoxide poisoning. Carbon monoxide is odorless and colorless. So if you were exposed to carbon monoxide, you might not even know it.
Will the oven still work without the light? Technically, yes your oven should still get hot if your light has stopped working. However, it will make your life considerably more difficult. You won't be able to identify whether or not your appliance is on, and you won't be able to tell when your food is cooked as easily!
The oven interior is designed to retain heat, even several hours after the oven has been turned off after cooking. The interior light may have been left on. The bulb can put off enough heat to warm the oven if left on.
Modern lights are safe to leave on for a week, though it isn't advisable. If you forgot to turn them off, LED bulbs are unlikely to overheat, trip electrics, or start a fire. On the other hand, incandescent, halogen, or fluorescent lights should never be left on for a week.
GE Range/Stove/Oven Main Control Board
The oven light often gets its power from the main control board. If the control board is shorted the light can stay on. If the light switch or door switch is in the off position, but the light stays on, the control board has likely shorted and will need to be replaced.
Most ovens have a light switch on the control panel so that you can check on cooking food without releasing heat by opening the door. Some ovens have a door-triggered switch so that the light comes on when the door opens and turns off when the door closes.
How long can an oven stay on before catching fire? If you have nothing in the oven, you can generally leave it on for about 12 hours safely if the temperature is low, the door is closed, and nothing flammable is near or inside of the oven. It is also important to make sure that your oven is reliable in this situation.
Odor and smoke when you turn on an oven for the first time is normal and not harmful. The best way to eliminate the smell is to run an empty cycle. It is recommended that you do not cook any food before this cycle as the smell and, potentially, the taste can stick with your food.
Many users tend to leave the range hood lights on for extended periods for convenience and as a form of kitchen lighting. This usage varies greatly among individuals, with some preferring the ambiance it creates and others utilizing it purely for functionality during cooking.
Remove the oven light bulb cover (see oven manufacturer's guide for exact steps) then use pliers to gently grip the base of the oven light bulb and apply light pressure to twist or pull the bulb out of the socket (depending on the make and model of oven).
While most commercial kitchens still rely on pilot lights for burners, ovens, and grills, current residential systems utilize an electrical ignition. This is more commonly known as standby on modern remote control fires.
The current standards for gas cooking products took effect in 2012. The standard prohibits standing pilot lights in all gas cooking products whether or not they have an electrical cord.
Most ovens have an indicator light
Once the oven has reached the temperature you have chosen,then the light will go out. The pre heating is completed and the food can be placed inside the oven to cook. If your oven does not have an indicator light please consult your instruction book.
Freestanding gas range models with an oven pilot ignition have a 1/8" flame. The amount of gas furnished to burn the oven pilot is minimal. If the pilot should go out, gas is immediately shut off to the main burner, however, there is still a small amount of gas that will continue to flow to the oven pilot.
